All precipitation products on the map above are valid for the previous day's precipitation estimate.
Global Precipitation Measurement (GPM) mission is an international network of satellites that provide global observations of rain and snow, built upon the success of TRMM. GPM was initiated by NASA and JAXA (Japan Aerospace Exploration Agency) as a successor to TRMM. GPM launched on Febuary 27, 2014 from Japan.
Global Satellite Mapping of Precipitation (GSMaP) was sponsored in 2002 by the Japanese Science and Technology Agency, and since 2007 the project is promoted by the JAXA team. GSMaP offers hourly global rainfall in near real time.
Tropical Rainfall Measuring Mission (TRMM)was launched in 1997 to study rainfall for climate and weather research. TRMM is no longer in orbit - the instruments were turned off on April 8, 2015. The multi-satellite product from TRMM is still being produced using in-orbit instrumentation and TRMM algorithms.
Climate Prediction Center (CPC) global precipitation analysis is a daily unified gauge based analysis of precipitation extending from 50N to 50S. This data is produced by NCEI (National Centers for Environmental Information).
